Acacia catechu, known as Khair is of great economical and commercial importance. Variable density yield tables of the species (plantation origin) has been prepared for proper management planning. Data were collected from sample plots laid out in Uttar Pradesh. Relationships between various characters were determined using multiple and simple regression technique. Tables based on these relations have been given for main and subsidiary crop by 5 year age class and from 10 through 60 years for three site qualities.

Eucalyptus hybrid has been planted extensively in India to meet the demand of fuelwood, small timber and pulp wood Growth aad production data of tbe first generation planted E. hybrid is available There is very little incomplete information avaiJable for Eucalyptus coppice of the first generation. For proper management planning of the coppice crop, growth and production statistics are nece ssary. This study provides required information for the first generation Eucalyptus coppice. Production table has been prepared by one year age class from 3 through 11 years for different stockings and two site qualities. Other crop characters such as crop diameter, basal area, M.A.I. and C.A.I. have also been given in the form of tables for different ages, site qualities and stockings.- Regional Volume Tables of Six Native Tree Species of North-eastern Region, India

Volume tables of six native tree species of north-eastern region of India have been prepared Grouping of species, based on similarity of bole form, has been adopted. Regression equations for total timber and total wood have been fitted. Models of the form V=a+b D2H and √V=a+b D has been found to give the best fit. Using these models, tables for total timber and total wood have been prepared.- Variable Density Yield Tables of Dalbergia sissoo (Plantation origin)

Dalbergia sissoo is a species of great economic and commercial value. It is raised both naturally and artificially. Variable density yield tables of the species (plantation origin) have been prepared to facilitate proper management. Data from sample plots laid out in Haryana, Rajasthan and Uttar Pradesh were collected. Relationships between various crop characters Were determined using multiple rerression technique. Results of analysis have been given. Tables based on these relations have been prepared for crop characters such as height, diameter, basal area (main crop), total wood volume (main crop) and total wood volume (rhinning). These tables are by 5 year age classes from 10 through 50 years for different densities and three site index classes.- Weight and Volume Tables and Volume-weight Relation for Poplar (Populus deltodes)

Volume tables of four important native species of north-eastern region of india namely (i) Amoora wallirhit. (ii) Zanthoxylum rhetea, (iii) Lagerstroemia parviflora and (iv) Tetrammeles nudiflora have been prepared. Relationships between volume, diameter at breast height and total tree height have been determined. Analysis of variance for each relation has been done. Models of the form V=a+b D2H and √V=a+b D were found to give the best fit. Based on these models, table for total timber volume and total wood volume have been given.- Regional Volume Tables of Dipterocarpus turbinatus Gaertn. f. (Based on the Data of Manipur State)
